长大隧道通风防尘和空气净化技术

Ventilation and Dust Prevention and Air Purification Technology of the Tunnel with Long Distance and Large Section

在调研长大隧道通风防尘与空气净化技术的基础上,结合山西省干阳沟隧道斜井通风工程施工技术,针对实际情况和参数进行计算和研究,确定采用水幕降尘与通风机配合使用的通风防尘和空气净化方案。论文阐述了长大隧道施工中关于通风方式、设备选型、通风管理及控制扬尘等方面的研究及实践成果。

Based on the investigation of ventilation and dust prevention and air purification technology of the tunnel with long distance and large section, combining with the project of Ganyanggou tunnel No.2 inclined shaft ventilation construction technology in Shanxi province,according to the actual situation and parameters, after calculating and researching, we determine to use the ventilation and dust prevention and air purification scheme which is using the water curtain dust and ventilator together. This paper explores the researches and practice result of ventilation method, equipment selection, ventilation management, dust controlling and so on.
